use a satellite?

Then today is your day to mourn.

Arthur C. Clarke has died.

I won't spend much time regurgitating what you can already find; just take a minute to think about the impact on culture, science and technology that Clarke has had.

I would have to say that the Clarke Belt, the geosynchronous orbit place around the earth, was by far the coolest thing, as it was only hypothesis back in 1945, and now it basically allows satellites to run our lives (think GPS, think telecoms, think Sirius).
